how soon can a blood test tell if you are pregnant? i had to go to the hospital yesterday because i fell and hit my head on concrete and had a really bad injury. i had to get a cat scan so i asked them to do a blood test to make sure i wasnt pregnant first so it wouldnt hurt the baby. the blood test came back negative. i think id only be 2 weeks pregnant, so is that too soon for even a blood test to be accurate? they shielded my stomach during the cat scan just in case anyway ( we did it before the results came back). please, someone let me know if thats too soon for even a blood test to be accurate???? id really appreciate any information anyone has

If by "2 weeks pregnant" you mean 2 weeks past conception,then that would be considered 4 weeks pregnant,which is already detectable by a HPT,so for sure it'd been picked up by blood test.

no by 2 weeks pregnant i mean 2 weeks pregnant. as in starting from my last period. i should be getting (or hopefully not in this case) my period on the 5th of this month. which would mean a home pregnancy test would not be accurate yet either.

If af is suppose to show on the 5th then you would only be about 9 days pg (if you are). And If they did the test were it just says yes or no then it wouldn't show up, but if they did the test were it says how much hcg is in your body it should have came up

all it said was negative. so that means it was a yes/no test right? it didnt have any levels on it.
